JAMES J. HoINTYRE, OF IRONTON, OHIO.

GAS-LAMP.

Specification of Letters Patent.

Patented Nov. 26, 1907.

Application filed July 25. 1906. Serial No. 327,728,

To all whom it may concern:

Be it known that 1, JAMES J. McINTYRE, a citizen of the United States,residing at Ironton, in the county of Lawrence and State of Ohio, haveinvented a new and useful Gas-Lamp, of which the following is aspecification.

This invention has relation to gas lamps and it consists in the novelconstruction and arrangement of its parts as hereinafter shown anddescribed.

The object of the invention is to provide a lamp which is attached to agas supply pipe and is provided with a central gas distributing chamber.A plurality of burners are mounted upon the said chamber and the supplyof gas from the chamber to the burners is governed in each instance by aneedle valve. A cone valve is interposed between the gas supply pipe andsaid gas distributing chamber and is adapted to move vertically inseating and unseating. A coil spring actuates the said valve to closethe same against the seat. The said valve is provided with a by-passvalve which permits a small quantity of gas to pass at all times fromthe supply pipe into the distributing chamber. The said distributingchamber is provided with a series of pivoted brackets. Said brackets areadapted to swing upwardly and permit the globe to be slipped above thedistributing chamber. The brackets are then swung down when the globe isseated upon the same.

In the drawing, the figure is a vertical sectional view of the lamp.

The gas supply pipe 1 has attached to its lower end the drum 2 whichconstitutes a gas distributing chamber. The conical seat 3 is located atthe lower end of the pipe 1. The plug 4 is screw threaded into thecenter of the under side of the said drum 2. The bush 5 is screwthreaded into the center of the said plug 4. The valve stem 6 isslidably located in the said bush 5. The upper end of said stem isprovided with a conical valve 7 which is adapted to close the seat 3.The said valve 7 is provided with the bypass 8 one end of which islocated within the pipe 1 and the other end within the gas distributingchamber 2. The coil spring 9 is interposed between the plug 4 or thebush ing 5 and the lower surface oi the said conical valves 7. Thetension of said spring is such as to have a tendency to maintain thesaid valve in an elevated position.

The yoke 10 is attached to the lower side of the plug 4 and is providedat each of its sides with the stops or pegs 11, 11. The lug 12 isattached to the valve stem 6 and is located below the bush 5 and isadapted to pass un der the stops or pegs 11. The key 13 is made to fitupon the lower end of the stem 6. The drum or gas distributingcompartment 2 is provided with a series of gas outlets and burners andas they are all of the same construction, a description of one willanswer for all. The bushing 14 is screw threaded into the top of thedrum 2. Said bushing is provided in its interior with a valve seat 15.The needle valve 16 is adapted to close or cooperate with the valve seat15. The said needle valve is screw threaded into the bushing 17 which inturn is screw threaded into the bottom or lower portion of the drum 2.The stufling box 18 surrounds the stem of the valve 16 and enters thebushing 17. The burner 19 is attached at its lower end to the bushing 14and is provided with the usual air ports 20 and the burner proper 21.The brackets 22 are pivoted at their inner ends to the lugs 23, saidlugs in turn being attached to the vertical walls of the drum 1. Thesaid lugs are adapted to swing in an upward direction only. That is tosay, they may swing down until they assume horizontal posit-ions whentheir downward movement is checked. The globe 24 in being seated uponthe brackets 22 is slipped up around the drum 2 when the brackets 22 areswung up and when the lower edge oi the said globe 2 1 is above the endsof the said brackets, the said brackets swing down when the globe may beseated at its lower edge upon the same.

It will be noted by referring to the drawings that the pegs or stops 11are disposed in two columns, those in one column being located oppositethe spaces between those in the other column so that by placing the lugs12 in engagement with one of the pegs or stops in either column a veryminute adjustment of the valve will be obtained. Moreover, by simplyreleasing the lug 12 from one of the steps 11 the valve 7 can bepromptly seated without further rotary movement.

Having described my invention, what I claim as new and desire to secureby Letters Patent is:

A gas lamp comprising a supply pipe, at gas distributing drum attachedto the end thereof, a plurality of burners mounted upon the drum anddisposed around the supply pipe, said drum serving as a source of supplycommon to all of the burners, a valve for controlling the supply of gasfrom the drum to to seat the valve immediately subsequent to the releaseof the lug from any one of the, stops. v p

In testimony that I claim the foregoing as 15 my own, I have heretoaflfixed my signature in the presence of two Witnesses.

JAMES J. MOINTYRE.
